RASPBERRY Pi1541 HAT with ROTARY ENCODER

(DIY COMMODORE 64 DISK DRIVE EMULATOR)

Hello,

This is a tested and working project.

This is an Easy DIY project, all components are through hole, marked on the PCB, Easy to solder, Easy to make ;)

Pi1541 is a real-time, cycle exact, Commodore 1541 disk drive emulator. You can load and save commodore64 programs, D64 .PRG ... extensions games/software from a Micro SD card, it is an alternative to SD2iEC, for more info please look at this link.

The source page link of this PCB drawing is below. (Option A)

It should also work with other suitable Raspberry Pi models listed at the source page.

Do not forget: solder 2 x 20 pin female header and 2pcs. 3 pin 11mm male headers before OLED display :)

SETTINGS FOR Pi1541 HAT DISPLAY PIN ORDER:

For VCC-GND-SCL-SDA Displays; SHORT VCC + VCC

For GND-VCC-SCL-SDA Displays; SHORT GND + GND

SETTINGS FOR ROTARY ENCODER:

Disable: no jumper

Enable: J1 and J2 with jumper (please look at the images)

(Rotary Encoder works fine with Raspberry Pi Zero 2W but not working properly with Raspberry Pi Zero.)

You can download sample SD Card files from the bottom of this page.

In order to protect your electronical devices, always turn off your Commodore before connecting or disconnecting the cables or any other device.

While transfering data (reading or writing) from SD cards it should not be interrupted like power-off or Reset systems. Otherwise that may damage SD cards.

Gerber files and component list are subject to change without notice. Before paying for the PCBs, be sure to update your orders!

As you can see I have uploaded many projects and I am still working on new projects. If you have any questions, please look for answers online. Unless I specify explicitly, all my projects are tested and confirmed to work under normal circumstances before being shared. I'm sorry I didn't have enough time to answer all the questions.

Use this PCB at your own risk !

Have fun

Thank you.
